How to increase disk capacity of elasticsearch nodes?

Elastic Stack Elasticsearch
1

Hello everyone, I want to increase the disk capacity of Elasticsearch data nodes. For this, I expect it to forward the shards on the node to other nodes using "cluster.routing.allocation.exclude._ip":"192.168.x.x" first. After all shards are transferred to other nodes, I shut down the server and add disks. This method takes a lot of time.

How can I increase the disk capacity of my nodes quickly and reliably?

Add a new node with the larger disk space, move shards from an old node to it, remove the old node.

That's as quick as it will get. There's no magic short cuts for this.
